Nuxt 405 error on generate and build for production

Question

When running nuxt generate the app will return a 405 error, I believe for each of the /api routes that exist. generate error pic. Its deployed with gh-pages -d dist to GitHub Pages w/ custom domain. 404 and 405 errors are returned when trying to access a page which makes axios calls to /api routes. production error pic. The app runs fine on localhost:3000 and can make all GET and POST calls to /api routes successfully.Tried tinkering with the nuxt.config.js but with no luck. It's possibly narrowed down to the nuxt.config.js settings and probably something to do with the production URL. Let me know what else I can provide to help you help me. Thanks.

Tried altering setup in nuxt.config.js (axios, path, URL, router, build)
